Sonder (uncountable) (neologism) The profound feeling of realizing that everyone, including strangers passing in the street, has a life as complex as one's own, which they are constantly living despite one's personal lack of awareness of it.
This is insightful as it brings a sense of introspection and humanizes the "other" unknown people around us as deserving the same level of respect we expect from others, while the NPC concept when applied to daily life does the opposite.
